[Q] Forensic Science question

[Actual Size]

1. What three chromatographic techniques are most applicable for solving analytical problems typically encountered in the crime laboratory? What is the main advantage of each? I'm not looking for the entire answer just someone to give me the ability to start and where to go to answer this.

Well, first we need to know just what are the "problems typically encountered in the crime laboratory?"

 

Surely DNA analysis must be in the top three.

 

I don't know what they use these days, but I think it's still some sort of PAGE

(poly-acrylamide gel electrophoresis).

 

#'s 2 & 3?

hello Actual size,

I have been mulling over this since yesterday and opted for this-

 

let's first decide what 3 common or typical crimes would pose themselves for this discussion.

How about, murder victim, rape victim,and dna testing for possible suspect involvement from the accused perpetrator.

Given that we will be using analytical chromatography,

these would seem viable.

I suggest that you go to Wikipedia for your search on the different applications. Query chromatography and choose 3 types that you may find applicable.

Present them here and lets discuss the possible advantages or disadvantages to each process.

Bear in mind for your choices, that some of these cases may be time sensitive, so a lengthy process, may allow a potential perpetrator to go into hiding, or cover over any other possible trace.Your best time to gain as much evidence as possible is in the first 48 hours after the crime has been commited.
